What is Ransomware

Ransomware is computer malware that installs covertly on a victim’s computer, executes a cryptovirology attack that adversely affects it, and demands a ransom payment to decrypt it.

How is works

The malware encrypts the victim’s files, making them inaccessible, and demands a ransom payment to decrypt them. The ransomware may also encrypt the computer’s Master File Table (MFT) or the entire hard drive. Ransomware attacks are typically carried out using a Trojan that has a payload disguised as a legitimate file.

There are two types of ransomware:

Lockscreen ransomware shows a full-screen message that prevents you from accessing your computer or files. It claims that you need to pay a ransom to gain access to your computer/files again.

Encryption ransomware changes your files so you can’t open them. It does this by encrypting the files.

Ransomware can get on your computer from the same sources that any other malware (including viruses) can come from. This includes:

• Visiting unsafe, suspicious, or fake websites.
• Opening emails and email attachments from people you don’t know, or that you weren’t expecting.
• Clicking on malicious in emails, social media posts and Instant Messaging chats.

Encryption ransomware is very difficult to get rid of from your computer, that’s why the best solution to ransomware is to be safe on the Internet and with emails and online chat:

• Don’t click on a link on a webpage, in an email, or in a chat message unless you absolutely trust the page or sender.
• If you’re ever unsure – don’t click it!
• Often fake emails and webpages have bad spelling, or just look unusual. Look out for strange spellings of company names or unusual spaces, symbols, or punctuation
• Maintaining a strong firewall and keeping your security software up to date are critical. It’s important to use antivirus software from a reputable company
